Specular Reflection ATR Accessory

Technical Details
- Compatible with standard 2” x 3” slide mount holders
- Dimensions: 8 cm x 5 cm x 4 cm (height x width x depth)
- Wavelength range from UV to far-IR
- Angle of incidence: 20°
- Material: Polyamide

Spectral Characteristics
The Specular Reflection ATR Accessory is perfect for liquids and soft samples and can be used for a wavelength range from UV to far-IR. The angle of incidence is 20 degrees.
Components
The Obsidian accessory system consists of the core module and a universal top plate. The IRUBIS crystals fit perfectly into the recess. Depending on your samples and application, you can choose between add-ons to modify your top plate.

Plate with Well
You can increase the volume capacity by mounting an additional plate on the universal top plate.
Recommended use: liquid samples, larger volumes
Please note: The plate is made of synthetic resin. Do not use acetone for cleaning.

Flow Cell
For continuous monitoring a flow cell can be mounted on the base plate. A channel with a diameter of 2 mm inside the cell directs the liquid sample to the crystal.
The assembly is simple and allows easy cleaning of the crystal and the cell after measurement.
Please note: The sealing for the flow cell is made of EPDM. The flow cell is made of synthetic resin. Do not use acetone for cleaning.
